seachBar=[[UISearchBar alloc] init];
//修改搜索框背景
seachBar.backgroundColor=[UIColor clearColor];
//去掉搜索框背景
//1.
[[searchbar.subviews objectAtIndex:0]removeFromSuperview];
//2.
for (UIView *subview in seachBar.subviews)
{
if ([subview isKindOfClass:NSClassFromString(@"UISearchBarBackground")])
{
[subview removeFromSuperview];
break;
}
}
//3自定义背景
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"40-di.png"]];
[mySearchBar insertSubview:imageView atIndex:1];
[imageView release];
//4输入搜索文字时隐藏搜索按钮，清空时显示
- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar {
searchBar.showsScopeBar = YES;
[searchBar sizeToFit];
[searchBar setShowsCancelButton:YES animated:YES];
return YES;
}
- (BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar {
searchBar.showsScopeBar = NO;
[searchBar sizeToFit];
[searchBar setShowsCancelButton:NO animated:YES];
return YES;
}
//改变搜索按钮文字
//改变UISearchBar取消按钮字体
for(id cc in [searchBar subviews])
{
if([cc isKindOfClass:[UIButton class]])
